  1. Hi Folks, Glad to hear this issue with "service 4WD" is not isolated to my 2019 Sierra Denali 1500. I First experienced it shortly after 3000Kms in wet snowy muddy highway conditions while in 4WD auto mode. The auto mode went from white to amber color and when i stopped the vehicle the E-Brake automatically applied. After driving on into better highway conditions the auto indicator light color, service 4WD light and E Brake all corrected itself. This has happen multple times since and i now have 12000 kms on the vehicle. I still haven't informed my dealer about this issue. The other issue is with "rabbits" apparently they love to chew on my block heater cord. I've had to shorten that cord a couple of times and wrap it with duct tape. Good luck everyone.
